Season 1 of 'The Walking Dead' was possibly one of the most intense seasons of television to air in a long time. Season 2 (premiering Sun., Oct. 16, 9PM ET on AMC) is over double the episodes, and according to the cast, double the scares and even more emotion.

"The scripts this year are unbelievably good," star Sarah Wayne Callies teased. "I mean, they have just knocked it out of the park."

Plus with character dying and turning into zombies all the time, they've gotten to bring in three new actors: Scott Wilson and Lauren Cohan (familiar with fanboy crowds already from her stints on 'Chuck' and 'Supernatural'), who'll play father and daughter Herschel and Maggie Greene, and Pruitt Taylor Vince who's playing the foreman at Herschel's farm where a lot of the Season 2 action takes place.

We caught up with the cast -- including Callies, Laurie Holden, Steven Yeun and Jeffrey DeMunn, as well as executive producer Gale Anne Hurd -- at the mecca of all things zombie, Comic-Con. They dished all about Season 2 drama, the heat (it's hotter than it was last year and there are ticks this season), some good relationships gone bad and romance in the air.

Zombies are known for eating brains, not using them.

But Gale Ann Hurd and Frank Darabont, the executive producers of 'The Walking Dead,' a zombie drama that debuts Sunday on AMC, faced in interesting intellectual challenge when it came to adapting Robert Kirkman's acclaimed graphic novels for television.

The goal was to stay faithful to Kirkman's story and to the gory undead genre, yet still attract viewers who may not be hardcore horror fans.

To make sure they channeled Kirkman's graphic novels, which tell the story of a sheriff and a few other people trying to survive in a zombified Atlanta, Darabont and Hurd consulted the author every step of the way. And though Sunday's pilot is ultra-tense, in subsequent episodes, 'The Walking Dead' evolves into a quest saga that won't be unfamiliar to viewers of 'Lost.'

"It doesn't hold back on the violence and gore, but what I think we're most proud of is that we were going for the emotional resonance as well with the characters," Hurd said in a recent interview.
